Benign essential blepharospasm (BEB) is a rare neurological disorder in which affected individuals experience involuntary muscle spasms and contractions of the muscles around the eyes. These spasms come and go (intermittent). Symptoms may begin as eye twitching, blinking and/or irritation. Eventually, BEB causes involuntary closure of the eyes. The exact cause of BEB is unknown. The disorder is one of a group of disorders collectively known as dystonia.
Dystonia is a group of movement disorders that vary in their symptoms, causes, progression, and treatments. This group of neurological conditions is generally characterized by involuntary muscle contractions that force the body into abnormal, sometimes painful, movements and positions (postures).
